It's great to have you join us and many thanks for your question.
I've made contact with James Hardie technical assistance and they have informed me that their current range of cement sheeting would only last a few years underground as it is not suitable for that application. They have suggested a product specifically designed for this purpose like Whites 600mm x 5m Recycled Garden Root Barrier and Whites 300mm x 8m Recycled Garden Edging would be much more effective.
Please let me know if you need further information or had questions.
I've used the 300mm edging , works well, needs a bit of digging (you will find tree roots!), it can be a bit wavy, best to unroll first, measure and cut, then lay it flat on a concrete slab in the sun , with some weights on it, for a day to flatten it out. The offcuts are useful for making various things , (dog poop scoops etc), cuts easily with tinsnips & bends well with a hot air gun.
Hi, I followed these instructions but then it didn’t work as the drop is around 400mm so the garden edging was too short. What can I put between the soil and new timber fence to keep the fence from rotting and hold up the soil please? I also have to leave by gap for draining down to the front of the street.
Please refrain from making multiple topics about the same topic as it makes the forum harder for others to use and navigate. Please be assured we will provide the support you need.
@Jason Thank You! The first time I posted the topic, I could not see it anywhere. Are there two topics posted that are the same? Can you please send me the links to view them? In 'My Posts,' it only shows one.
There's just this one thanks @mrsgiveitago. The other two you posted have been removed by the moderation team.
Hi @Jason I have not received a response to my two topics and was hoping to do this work tomorrow please?
My apologies for the late reply. Due to your height requirements, you will need to double up the Cyclone 250mm x 3.2m Corrugated Garden Edging. You can join them together by using a Craftright Rivet Gun Set. Put the Garden Edging on top of one another and have them overlap by 30mm. Drill pilot holes on both Garden Edging panels and use rivets to join them together. This will now give you the height that you need to hold the soil back.
Please note that the Garden Edging will need to be supported from the back to keep it upright. I suggest using 900mm Hardwood Garden Stake - 6 Pack. However, if the timber posts are not strong enough to hold the soil back you will have to use Whites 90cm Premium Black Ultrapost. I've placed a sample diagram below for you to look at. If you have any questions about it or need further assistance, please let me know.
